Subject Error starting ResourceManager with hadoop-2.0.3-alpha
Date Thu, 21 Mar 2013 14:57:50 GMT
Hi,

  I had been using hadoop-2.0.0-alpha since quite sometime which I think I
downloaded around June/July last year. Now I am trying to shift to the
latest version hadoop-2.0.3-alpha and while starting it up in the similar
way as the old one, I am getting the following error in Resource Manger's
log file and it is not starting up.
